You can, just not all at once.
And which plan 9 release and when? Ghostscript and Python were originally distributed with 9front which are both HUGE compared to the rest of the system. Remove those and its much, much smaller. Unsure if ghostscript was included in vanilla 9 from the labs. Python was included in 9front because it was necessary for mercurial. Once git9 arrived python was nuked from base and removed many lines of code. Ghostscript is next to go from base once pdffs is running (patches welcome.)
